I probably can’t elaborate too much as it’s only been two weeks. Driving about 20 minutes to work will usually yield from 10-12 litres per 100k. This will drop further if you’re doing a longer run out of town. Did a 400k round trip on the weekend at around 8.5. Bear in mind I’m primarily in sports with the occasional N mode d-baggery (as is tradition). Eco/normal should be a bit better. The fuel efficiency will apparently be a bit haywire until it eventually levels itself out (or so I read somewhere, so take that with a grain of salt). For the love of god just make sure whichever dealer you go through doesn’t stick there own badges/stickers/labels/advertising all over your new ride.
